Problem:Usually when we click on the close menu of web-part it is disappear from screen. I want to display a window in which all the web-parts which were disappear so user can select and get back ?
Solution:
Just put a CatalogZoneWebPart with PageCatalog inside it and after running the appliaction you’ll find that your closed WebPart is in CatalogZone. Just mark check the ClosedWebPart and you’ll restore this.
